This inventionrelates to improvements in washing machines and is directed particu 't larl')1 `tothe provision of novel agitating 1 means therefor. 5 The. present invention is specifically directed'to the structure and com 'tion of an'agitator and for purposes of 'illustration is herein shown in connection with an agi- 'tating means that o rates at the bottom of Vlothe .container for e purpose of inducin .lateral deectionandupward projection o theiluidcontent. v

The invention also includes'service utility because of the nature ,of the 'tator strucf ture as a whole being develop from a material lighter than metal, as for instance a condensation roduct whichisasubstitu or synthetic whereby the shock attending reversing action of. the agitator may be 2o minimized to thesmallest possible degree.

'A further advantage of the applicants dolly is that much-of the noise incident to the operation of former washing machines of this type is eliminated by its use.

Still another'very im rtant advantage is that the applicants do y is a non-absorber and non-conductor of heat. 1 This has the advantage thatJ the bearings on which the doll is mounted are shielded from the heat of e washing fluid or water, and that the dolly itself may be readily removed immediatelyafter the termination of the washingrgperation if desired. Y y e above description, it is thought, fully lpresents the material features of advantage o'f the r tator herein, and presents a preferable orm vof embodiment. However;

other characterstics of service and advan-V tage are obviously included within the `ta tor structure, and with respect to theuirm resented, it is similarly obvious that other orms may be employed that may serve measurably to perform the vfull functionsof that of the disclosure, and hence all structures and forms of structures g the utilities herein presented are imed as set forth.
